Used primarily as an intermediate in the synthesis of conjugated polymers for organic electronics. It plays a key role in the development of organic semiconductors used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The bromine functionality allows for coupling reactions, such as Stille or Suzuki coupling, enabling the construction of complex polymer chains with tailored electronic properties. Its octyl side chain improves solubility in organic solvents, which enhances processability during device fabrication. Commonly employed in research settings to optimize charge carrier mobility and thin-film morphology in printed electronics.
